changing password in php

[tomex]

i have a code in php that changes password. it runs smoothly no errors, but the question is it does not update the passoord on the database??

here is the form $s is the session ID

<?php echo"
<form action = \"chpw.php?d='$s'\" method = 'POST'>
NEW PASSWORD: <input type='text' name='pass'>
<br/>
<input type='submit' value='Submit Password'><br/>
</form>"; ?>
 

here is the script that updates

<?php
 
//$password = md5($_POST['pass']);
//$s=$_GET['d'];
//$s=$_POST['id'];
 
if(md5($_POST['pass'])== ''){
echo ('invalid password');
}else
$sql="UPDATE account SET Password='".md5($_POST['pass'])."' WHERE StudId='".$_GET['d']."'";
$result=mysql_query($sql);
    if (!$result)
        die('Error: ' . mysql_error());
 
echo "Password Changed Successfully!<br><br>\n";
header('location: pwlogout.php');
exit();
 
?>
 
 

i have tried anything and still to no avail please help thank you

im not sure what you meant by

here is the form $s is the session ID

is it the PHP session id? if so you are using the php session id as the
StudId. so probably that is not right.

and it is not ok and (not useful) to echo something before the header()
so remove the header()

echo "Password Changed Successfully!<br><br>\n";
header('location: pwlogout.php');
exit();
 

and your if condition is not properly written

do not check the md5 converted string is empty because it will never be.

and the else condition is not well planned. use { (curly braces) properly



anyway please edit you script in the following way

<?php
 
//$password = md5($_POST['pass']);
//$s=$_GET['d'];
//$s=$_POST['id'];
 
if($_POST['pass']== '')
{
    echo ('invalid password');
}
else
{
    $sql="UPDATE account SET Password='".md5($_POST['pass'])."' WHERE StudId='".$_GET['d']."'";
 
    echo $sql;
 
    $result=mysql_query($sql);
    if (!$result)
        die('Error: ' . mysql_error());
 
    echo "Password Changed Successfully!<br><br>\n";
    //header('location: pwlogout.php');
    exit();
}
?>
 

and check the sql which was generated, see if all the variables are
replaced properly and the way you wanted

paste the result here if you can so i can analyse it.
